Senior🎓
Top SchoolGagan Kumar is a Senior Software Engineer in Site Reliability Engineering at Google with 11 years of experience building and operating large-scale production networks and infrastructure. He has deep SRE experience on Google’s Production Backbone (AS15169) and a track record of shipping networking and QoS features from his Arista internship through to production-focused roles at D. E. Shaw and Google. A strong systems programmer and backend contributor, he has improved grading and submission workflows in the well-regarded open-source Submitty project and still mentors students from his competitive programming roots. Gagan pairs rigorous academic training from IIT Patna (9.53/10) with practical experience across C++, Python and Go, and a history of contest finals (Google Code Jam, Facebook Hacker Cup, ACM ICPC regionals) that sharpen his algorithmic instincts. Based in Sunnyvale, he blends low-level networking expertise with automation and observability practices to keep critical services reliable. Less obvious: he continuously channels competitive and community work—organizing contests and contributing to OSS—into scalable tooling and mentoring.
